| stalked hydatid | A small fluid-filled cyst attached by a slender stalk to the fimbriated end of the uterine tube; a vestigial remnant of the embryonic mesonephric duct. Synonym: appendix vesiculosa, Morgagni's hydatid, morgagnian cyst, stalked hydatid, vesicular appendage. (05 Mar 2000) |

| osseous hydatid cyst | A morphological form of hydatid cyst caused by Echinococcus granulosus, and found in the long bones or the pelvic arch of humans if the embryo is filtered out in bony tissue; in this site no limiting membrane forms and the cyst grows in an uncontrolled fashion, producing cancellous structures and inducing fracture, followed by spread to new sites. (05 Mar 2000) |
| unilocular hydatid cyst | The commonest form of hydatid cyst in man, caused by Echinococcus granulosus and found in the liver, lungs, or any other site where the hexacanth embryo may settle if it passes the hepatic or pulmonary capillary filters; characterised by large balloon-like forms lined internally with a germinative membrane, enclosed externally in a laminated membrane within a host-parasite capsule, and filled with fluid (hydatid fluid) and infectious scoleces of the young tapeworms (hydatid sand).

| Morgagni's columns | A number of vertical ridges in the mucous membrane of the upper half of the anal canal formed as the caliber of the canal is sharply reduced from that of the rectal ampulla. Synonym: columnae anales, Morgagni's columns, rectal columns. (05 Mar 2000) |
| Morgagni's concha | The upper thin, spongy, bony plate with curved margins, part of the ethmoidal labyrinth, projecting from the lateral wall of the nasal cavity and separating the superior meatus from the sphenoethmoidal recess, the above bony plate and its thick mucoperiosteum, which is less vascular than that of the middle and inferior conchae. Synonym: concha nasalis superior, Morgagni's concha, superior turbinated bone, turbinated body. (05 Mar 2000) |
| Morgagni's crypts | The grooves between the anal columns. Synonym: Morgagni's sinus. Pockets or crypts in the columnar zone of the anal canal between the anocutaneous line and the anorectal line; the sinuses give the mucosa a scalloped appearance.
